Help me PLease also explain how to do it

Answer 1

❥$\Large\pmb{ \underline {\tt Answer}}$

So we can only find x if other two angles of triangle is given.

In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.

We know sum of angles of triangle = 180°

{Reson :-

There's a formula to fund sum of angles of figure

• (n-2) × 180
• (3 -2) × 180
• 1 × 180
• 180°

}

Now Let's proceed

$\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}$

Fill all the given values

$\dashrightarrow \tt 90 \degree + 55 \degree + c = 180 \degree$

$\dashrightarrow \tt 145\degree + c = 180 \degree$

$\dashrightarrow \tt c = 180 \degree - 145\degree$

$\dashrightarrow \tt c = 35\degree$

Value of x = 35°
